What separates Toney and Hopkins is that they had really solid fundamentals and great ring I.Q (which don't really diminish with time). Roy had neither; his main attributes were his godly speed and amazing reflexes, which by the way evaporate very quickly.

That so wrong! Roy has a very high boxing IQ. Roy's fighting style however was tailor made for a young fighter. His style didn't work well when the body got old. Its not that he didn't have great skills as a boxer, he just had a weird style of using those skills...and it caught up with him when he got old.
